CALVIN B. PATCH, OF GLENELLYN, ILLINOIS, ASSIGNOR TO WILLIAM H. MINER, OF

CHAZY, NEW YORK. p v I RAILWAY-GAR SIDE BEARING.

Application filed July 14, 1916. Serial No. 109,234.

To all whom it may concern Be it known that I, CALVIN B. PATCH, a

i citizen of the United States, residing at Glenellyn, in the county of Dupage and State of Illinois, lave invented a certain new and useful Improvement in Railway- Car Side Bearings, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvementsin railway car side bearing. 7

One object of the invention is to provide a simple, relatively cheap roller side bearing for railway cars and so arranged that the roller will be automatically returned to central or normal position after each actuation.

In the drawing forming a part of this specification, Figure 1. is an end elevation of portions of a truck and body'bolster of a car showing my improvements in connection therewith. Fig. 2 is an enlarged, longitudinal vertical section of the side bearing properv taken on the line 22 of Fig. l. Fig. 3 is a vertical transverse section-taken substantially on the line 33 of Fig. 2. And Fig.

4 is a perspective view of one of the spring followers.

In said drawing, 10 denotes the body bolster and 11 the truck bolster which are pivotally connected at their centers in the usual manner. As shown, the body bolster is provided with a striking plate 12 and the truck bolster has applied thereto the improved side bearing designated generally by the reference A.

The improved side bearing A preferably comprises a base member or casting B which is riveted or otherwise suitably secured to the truck bolster, and an anti-friction roller 0. The base member B is of substantially" box-like form, open at the top, and has,out wardly extended bottom flanges 13 through which pass the securing means, and on its interior, the base member is provided with a suitable inserted tread or wear plate 14 on which the roller C operates.

The roller retaining plate or base casting B has parallel side walls 15-15 and curved end walls 1616 which limit the movements of the roller C. The roller 0, as shown, comprises two sections C and C connected by a central axle or journal 17 of reduced Specification of Letters Patent.

diameter. Each of the end walls 16 ofthe base casting is provided on its interior with a boss 18 within which is slidably mounted a non-circular bar 19 headed at its inner end asindicated at 20. Slidably mounted on each of said bars 19 at their inner ends, is a spring follower 21 which fits between the sections O and C of the roller and engages the central axle portion 17, each follower 21 being curved on its inner face to lit the axle portion 17; Also mounted on eachof said bars 19 is a spring 22 which together cooperateto maintain the roller C in central or normal position.

Upon movement of the roller to either sideof its normal position, one of the followers 21 and the bar 19. by, which it is carried,

will be forced outwardly against the action of the spring 22. Upon release of the pres? sure on the roller, the spring 22will expand, thus forcing the roller back to central position and returning the bar 19 and its corresponding spring follower to normal position. i

I claim:

1. In a roller side bearing, the combination with a base casting, of a roller mounted within said base casting, the roller comprising two sections spaced apart and united by a central portion of reduced diameter, oppositely arranged bars slidably mounted in the end walls ofthe base casting, the inner ends of said bars extending into the space between the two sections of the roller and springs for retaining said bars in normal position.

2. In a roller side bearing, the combinetion with a hollow base casting, a roller mounted wlthm said castlng, having a central P01131911. of reduced diameter, bars on opposite sides of said roller slidablymounted with respect to said'base casting, followers on the ends of said bars engagingsaid reduced portion of the roller, and springs mounted on said bars extending between the end walls of the base casting and said fol-- lowers. I

In witness that I claim the foregoingl have hereunto subscribed my name this'12th day of July, 1916.
